Clunking from rear on bumps...what the hell is it???

[DenaliAK]

Just like it says...when I go over big or sharp bumps, I hear a loud, solid metal-on-metal clunk. I've checked everything I can think of and everything seems tight. Shocks, exhaust, spare tire, rear seats....if it's in the back and metal, I've seen if it could move. I just have no idea what it is. Just had it serviced and they couldn't figure it out either, but said everything looks great (which it must since they normally try to get you to pay for "other" work).

I'm open to other ideas, suggestions, solutions, etc.

Thanks!

i believe it is the trailing arms, mine does the same thing, i believe some grease/lube will fix the problem...

 

[DenaliAK]

Thanks, I'll look into it. That'd be a nice and cheap fix.

The best way to find the problem is to have your wife or anyone else that is heavy enough, stand on the rear step pad and move in an up-dowm motion to simulate suspension dampening while you lay under the truck and find it.

Yeah, we've tried that but can't simulate the severity of the bumps needed to make the noise. Thanks for the idea, though.

LOL did you call his wife fat?

Hahaha...I hadn't even thought of that.

But not my wife....she's a sexy thang.

Haha mybad, I meant just don't get a 60 lbs kid to jump on it.

 

[DenaliAK]

No worries. Was kinda funny, though.
